Save Money, Manage Easier

Primary Rate Interface (PRI) lines connect your on-site private branch exchange (PBX) to the public telephone network. They offer you a dial tone, but they're limited and expensive to maintain. With only 23 outbound calls possible per PRI line, you probably own more than one to facilitate all your calling needs.

VirtualPBX SIP Trunking replaces all your PRI lines with a single service. It can handle a virtually unlimited number of outbound calls. And unlike a PRI, you can easily add or remove channels at a low cost. We also offer crystal clear call quality, industry-leading 99.999% uptime, 24/7 customer support, and low cost number porting.

Are You a SIP Trunking Candidate?

Almost any business with an on-site PBX makes a good candidate for SIP Trunking. You can keep your existing hardware and phone setup when you make the switch to VirtualPBX.
